Cosmetic applicator having an internal space containing the composition

Abstract

The present invention relates to a cosmetic applicator for applying a non-liquid composition (P) to human keratin materials, the applicator: —comprising a stem ( 7 ) that extends along a longitudinal axis (X), —defining an internal space ( 9 ) that is able to contain the composition (P) to be applied, and —having at least one opening ( 18 ) that is in communication with the internal space ( 9 ) and leads onto an application surface ( 8 ).

1 . Cosmetic applicator for applying a non-liquid composition to human keratin materials, the applicator:
 comprising a stem that extends along a longitudinal axis,   defining an internal space that contains the non-liquid composition to be applied, and   having at least one opening that is in communication with the internal space and leads onto an application surface.   
     
     
         2 . Cosmetic applicator for applying a composition to human keratin materials, the applicator:
 comprising a stem that extends along a longitudinal axis and bears an endless screw,   defining an internal space that is able to contain the composition to be applied, and   having at least one opening that is in communication with the internal space in order to dispense said composition,   wherein the endless screw turns inside the internal space such that its rotation causes the composition to flow through the opening(s).   
     
     
         3 . Applicator according to  claim 1 , which has a plurality of openings in the form of slots, in particular between 5 and 50 openings, better still between 10 and 20 openings. 
     
     
         4 . Applicator according to  claim 2 , wherein the endless screw comprises a body and protruding elements that are connected thereto and make it easier to dispense the composition. 
     
     
         5 . Applicator according to  claim 4 , wherein the protruding elements on the endless crew follow the same helical path as the thread thereof. 
     
     
         6 . Applicator according to  claim 4 , wherein the protruding elements on the endless crew are the same height as the thread thereof, being in particular between 0.5 mm and 1.5 mm, better still between 0.7 mm and 1.2 mm. 
     
     
         7 . Applicator according to  claim 4 , in which the clearance between the stem and the thread of the endless screw is between 0.1 mm and 4 mm, better still between 0.5 mm and 3 mm. 
     
     
         8 . Applicator according to  claim 1 , wherein the composition comprises fibres made of a thermoplastic material, in particular polyamide, with a length in particular of between 0.5 and 3 mm, better still between 1.2 and 2.1 mm, and with a diameter in particular of between 0.5 dtex and 5 dtex. 
     
     
         9 . Applicator according to  claim 2 , wherein the composition comprises flakes, in particular with a largest dimension of between 0.006 mm and 3 mm. 
     
     
         10 . Applicator according to  claim 1 , wherein the composition is a loose or pressed powder. 
     
     
         11 . Applicator according to  claim 1 , wherein, with the composition comprising fibres or flakes or being a powder, the ratio between the section of the openings in the applicator and the largest dimension of the solid particles of the composition is between 0.001 and 2, better still between 0.5 and 3. 
     
     
         12 . Applicator according to  claim 1 , wherein the composition comprises a binder, in particular with a content by mass ranging from 1% to 10% within the composition, comprising in particular at least one oil. 
     
     
         13 . Applicator according to  claim 1 , wherein the composition is a paste with a sufficiently high viscosity not to flow under the effect of its own weight. 
     
     
         14 . Device for packaging and applying a first cosmetic composition, in particular a makeup composition, to human keratin materials, comprising an applicator according to  claim 1  and a first container holding the applicator. 
     
     
         15 . Device according to  claim 14 , which comprises a second container containing a second composition, and comprises a second applicator comprising an applicator member that defines an application surface, the second applicator being in particular secured to the first applicator, the second composition being in particular other than a non-liquid composition. 
     
     
         16 . Method for making up or caring for human keratin materials with the aid of a packaging and application device according to  claim 14 , wherein use is made of an applicator to apply the non-liquid composition to the keratin materials, the applicator:
 comprising a stem that extends along a longitudinal axis,   defining an internal space that contains the non-liquid composition to be applied, and   having at least one opening that is in communication with the internal space and leads onto an application surface.   
     
     
         17 . Method according to  claim 16 , wherein the endless screw is turned inside the internal space of the applicator such that the rotation of the endless screw causes the composition to flow through the opening(s) in the applicator. 
     
     
         18 . Method according to  claim 16 , which comprises a step prior to the application of the non-liquid first composition to the keratin materials, of using the second applicator to apply the second composition contained in the second container to the keratin materials intended to receive the first composition.
